Manicure and pedicure file

ABSTRACT

A nail file in the form of an arc with generally rounded edges and a method for grooming finger- and toenails using the file.

TECHNICAL FIELD

The invention is in the field of files for use in manicuring andpedicuring.

BACKGROUND OF THE INVENTION

There are a wide variety of files available for use in grooming nailsand skin. The typical file is flat and planar, and tends to be elongatedwith rounded ends. Either one or both sides of the planar surface areabrasive, permitting both sides of the file to be used in grooming thenails or skin. Sometimes the abrasive surfaces on each side of the filediffer in texture and grain, with one side of the file having a roughergauge abrasive for more serious abrading, and the other side of the filea smoother abrasive surface for finer, more precision filing. One commonproblem when using such files is that the file must be held with thefingers, and the skin on the fingers themselves sometimes becomesabraded when holding on to the file. Also, it is sometimes difficult tohold the file itself when there are no areas that facilitate gripping.

Accordingly, there is a need for a file for use in manicure and pedicureprocesses that facilitates easy gripping, reduces the possibility ofincidential abrasion of superficial skin on the fingers, which isinexpensive to manufacture and easy to assemble and ship.

It is an object of the invention to provide a file for manicure andpedicure applications, which is in the form of an arc having at leastone attachment that facilitates gripping and use.

It is a further object of the invention to provide a file for manicureand pedicure applications that is in the form of an arc having a degreeof bend that facilitates gripping and use.

DETAILED DESCRIPTION OF THE DRAWINGS

The file 1 of the invention is an-elongated planar surface 2 in theshape of an arc 20A having generally rounded ends 3. The file 1 is bentvery slightly to form an arc 20A, having one long side edge that isconcave 20 with the opposite long side edge being convex 21 with sideedges joined by generally rounded ends 3. The degree of bend in the arcmay range from about 1 to 30 degrees, more preferably from about 1 to 20degrees, most preferably about 1 to 15 degrees with the degree of bendbeing determined by drawing a straight line 16 tangent to mid section16A, as depicted in FIG. 3, and measuring the angle between tangent line16 and file edge 16B. The arc 20A shape facilitates easier gripping ofthe file 1 as opposed to the traditional straight files, and enables theuser to better manipulate the file to treat the nails on the hands ortoes.

The file 1 has a top surface 4 and a bottom surface 5. Either one orboth of the top surface 4 and bottom surface 5 may have an abrasivesurface layered on. The abrasive surface may be made by gluing abrasivegrains such as sand, silicon dioxide, diamond grains onto the surfaces4, 5, or by overlayering and gluing an abrasive fabric onto the surfaces4, 5. The top surface 4 and the bottom surface 5 may have the same grainabrasive on the surfaces or, different grades of abrasive depending onthe applications. Generally, one embodiment is where top surface 4 has arough grain abrasive surface that makes it suitable for use insituations where heavy duty abrading is desired; and bottom surface 5has a finer grain abrasive surface that makes it useful in doing fineabrasive work, such as finishing work in filing the nails. Anotherembodiment is where both top surface 4 and bottom surface 5 have thesame grain abrasive surface. The term “grain” refers to the particlesize of the abrasive that forms the abrasive surface. The term “finegrain” means that the particle sizes are generally very small (forexample submicron sizes such as 0.0001 micron to 200 microns), and“medium grain” means that the particle sizes of the abrasive range from201 microns to 800 microns; and “rough grain” means that the particlesizes of the abrasive range from 801 microns to 1200+ microns.

Preferably the file 1 has a width 6 ranging from about 0.001 to 0.5inch, more preferably from about 0.001 to 0.25 inch.

The file 1 has an ergonomic attachment 7 that may be removably slippedonto the file 1, or is, more preferably, permanently affixed thereto inthe mid-section 8. Ergonomic attachment 7 preferably has a rounded topsurface 9 having a generally oval circumference 10, and which may begenerally convex 10A. Preferably half of the top surface 9 is striated11 or distressed, which in turn better facilitates gripping of the fileon ergonomic attachment 7 when the user 12 is using file 1 to file nails13 of the toes 14 or fingers 15. Ergonomic attachment 7 may be striated11 on only one side or on both sides. Preferably ergonomic attachment 7is striated 11 only on one side and the striations are about one half ofthe upper convex 10A surface.

FIG. 3 is a cross-sectional view taken across 3-3 of FIG. 2, and betterdepicts how ergonomic attachment 7 surrounds midsection 8 of file 1forming a convex surface 10A that facilitates gripping of both lower andupper sides of file 1. Preferably ergonomic attachment 7 has side edges17 that leave a portion 18 of file side 19 exposed.

File 1 may be used to file nails on fingers or toes as depicted in FIGS.4 and 5. The arc shape 20A in combination with ergonomic attachment 7makes the file 1 much easier to grip.

The invention is also directed to a method for grooming the nails offingers or toes by treating with a file 1 in the form of an arc 20Ahaving at least one ergonomic attachment 7 that facilitates use andgrip.

The file may be used to file the finger- or toenails, or it may be usedto gently abrade skin on fingers or toes.
